Comment Get another job, and become a sysadmin. (Score 1) 474
You'd probably need a BS CS before going for a decent MS CS.
The four tracks in front of you sound like, in order of probability:
1. Helpdesk Manager
2. System Administrator
3. Web Designer
4. Software Developer/Web Developer
System administrator is a jump you can make with a few certifications and/or a bit of luck. Web designer is a pretty full field, and it tops out pretty quickly. Web developer requires a touch more school in most cases.
Get another helpdesk job. Bounce between a few until you find one that's lower stress, and lets you learn what you want to learn in downtime. Strongly consider system administration, as you can get there from where you are the most quickly, especially in a company willing to promote from helpdesk to junior admin.
